This series implements 2 fixes to be able to use USB Ethernet gadget with the dwc3
driver.
It also adds new commands to bind/unbind a device to/from a driver and
update the 'dm tree' command to make it easier to use those new commands.
The bind/unbind commands can be used to bind the DWC3 USB gadget to the
usb_ether driver from the command line instead of relying on platform code.

Changes in v3:
- update some commit logs
- factorize code based on comments from ML
- remove the devices before unbinding them
- use device_find_global_by_ofnode() to get a device by its node.

Changes in v2:
- Make the bind/unbind command generic, not specific to usb device.
- Update the API to be able to bind/unbind based on DTS node path
- Add a Kconfig option to select the bind/unbind commands

Jean-Jacques Hiblot (7):
  usb: gadget: Add bcdDevice for the DWC3 USB Gadget Controller
  net: eth-uclass: Fix for DM USB ethernet support
  uclass: Add dev_get_uclass_index() to get the uclass/index of a device
  dm: print the index of the device when dumping the dm tree
  dm: convert device_get_global_by_of_offset() to
    device_get_global_by_ofnode()
  device: expose the functions used to remove and unbind children of a
    device
  cmd: Add bind/unbind commands to bind a device to a driver from the
    command line
